5. The communication device according to claim 4 , wherein the evaluation determination part is further configured to: evaluate whether the tone of the voice falls within a range of a tone of a voice of a general conversation, and determine that the calling processing is performed when the tone of the voice falls outside the range.

6. The communication device according to claim 3 , wherein the evaluation determination part is further configured to analyze and evaluate a keyword of the first user's voice accepted by the input unit.

7. The communication device according to claim 6 , wherein the evaluation determination part is further configured to: evaluate whether the first user's voice includes a prescribed negative keyword, and determine that the calling processing is performed when the first user's voice includes the prescribed negative keyword.

8. The communication device according to claim 3 , wherein the evaluation determination part is further configured to analyze and evaluate an image accepted by the input unit.

9. The communication device according to claim 8 , wherein the evaluation determination part is further configured to: evaluate whether the first user's facial expression falls within a normal range when the image includes the first user's face, and determine that the calling processing is performed when the first user's facial expression falls outside the range.

10. The communication device according to claim 8 , wherein the evaluation determination part is further configured to: evaluate when the image includes a periphery of the first user's face, whether the image of the periphery changes, and determine that the calling processing is performed when the image of the periphery of the first user's face changes.

11. The communication device according to claim 3 , wherein the evaluation determination part is further configured to analyze and evaluate movement of the communication device itself, the movement being accepted by the input unit.

12. The communication device according to claim 11 , wherein the evaluation determination part is further configured to: evaluate whether one of vibration and pressure at a prescribed reference level or higher is applied to the communication device, and determine that the calling processing is performed when one of the vibration and the pressure at the reference level or higher is applied.

13. The communication device according to claim 1 , wherein the first communication part is further configured to start the first communication with the end of the second communication.

14. The communication device according to claim 1 , further comprising: a first information supply part configured to control the communication unit to supply first information to the communication device of the second user associated with the virtual communication party, wherein the first information showing a content of the first communication started by the first communication part.

15. The communication device according to claim 14 , wherein the first information further includes one of a log of the first communication and a summary of the log.

16. The communication device according to claim 14 , wherein the first information further includes one of a color, a density, a pattern, a graphic, a text, and a symbol, each of which shows a content of the first communication.

17. The communication device according to claim 1 , further comprising: a storage part configured to store setting information of the virtual communication party therein, wherein the first communication part is further configured to generate, using the setting information stored in the storage part, the response by the virtual communication part to the first user's input accepted by the input unit to start the first communication.

18. The communication device according to claim 17 , further comprising: a setting information acquisition part configured to acquire the setting information from another device, wherein the storage part is further configured to store the setting information acquired by the setting information acquisition part therein.

19. A communication method, comprising: generating a response by a virtual communication party to an accepted first user's input and outputting the generated response to start first communication between the first user of the communication device and the virtual communication party in a state in which the communication device is not connected with any other communication device; performing calling processing on a communication device of a second user associated with the virtual communication party to call the second user when the first communication is started; and supplying the accepted first user's input to the communication device of the second user having responded to the calling processing; acquiring a response to the first user's input from the communication device of the second user; and outputting the acquired response to start second communication between the first user of the communication device and the second user.

20. A non-transitory computer-readable recording medium having a set of computer-executable instructions recorded thereon, the instructions causing a computer to function as: a first communication part configured to: generate a response by a virtual communication party to a first user's input accepted by an input unit, and output the generated response from an output unit as one of an image and a voice to start first communication between a first user of the communication device and the virtual communication party in a state in which the communication device is not connected with any other communication device; a calling processing part configured to: control a communication unit to communicate with another device, and perform calling processing on a communication device of a second user associated with the virtual communication party to call the second user when the first communication is started by the first communication part; and a second communication part configured to: control the communication unit to supply the first user's input accepted by the input unit of the communication device to the communication device of the second user having responded to the calling processing of the calling processing part, acquire a response to the first user's input from the communication device of the second user, and output the acquired response to the output unit to start second communication between the first user of the communication device and the second user.
